Claims.

This invention relates to hangers for doors and concerns itself moreparticularly with hangers for use with sliding car doors of the flushtype. -'It is among the objects of this invention to 5 provide a hangerfor sliding car doors which shall door, each of said rods having anoperating lever adjustably secured theretoto insure proper seating ofsaid door in its door opening.

Another object of the invention is the provision of a door hangercomprising a plurality of vertical bars rotatably secured to said door,each of said bars carrying'an operating lever, and means mounted on saiddoor for automatic engagement with said levers when the latter areoperated to remove the doors from their openings to effect smoothunimpeded sliding movement of the doors.

''Other objects will appear as the description of this inventionproceeds.

In the drawings forming a part of this specification:

Figure 1' is a fragmentary elevation of a house car illustrating a doorsupported upon a hanger embodying this invention.

Figure 2 is a vertical sectional view taken on line 2-2 of Figure 1, thedoor being shown removed from its opening in dot and dash lines.

Figure 3 is a horizontal section taken on line 3--3 of Figure 1.

Figure 4 is a view. similar to Figure 3 showing the door removed fromits opening and in position for sliding movement.

Figure 5 is a detail in elevation of a combined bearing and latchmember.

Figure 6 is a top plan view of Figure 5.

Figure? is a detail of a hook utilized in the combined bearing and latchmember.

Figure 8 is an enlarged partial elevation looking in the direction ofthe arrows 8--8 shown in Figure 4 of the drawings.

Referring to the drawings in which a preferred embodiment of thisinvention is illustrated thenumeral 10 indicates generally a house car.There is provided in the car 10 a door opening defined by the verticaldoorposts 11 and 12 and by a lintel 13 and threshold 14. As clearlyshown in Figures 2, 3 and 4, the car illustrated is pref erably arefrigerator car.

A door 15 may be used to close the opening in the car. This doorcomprises essentially a metallic construction. It embodies an outermetallic plate 16 formed preferably of a plurality of dished panels 17and 18. These panels provide horizons. tal corrugations 19 and 20 andvertical corrugations 21 and 22. The door construction fur ther embodiesan inner metallic plate 23 spaced from the outer plate 16. An angularreinforcing frame 24, substantially Z shaped in-section; :is employed toconnect the inner'and outer'plates' in order'to constitute the main doorstructure; The inner and outer plates are preferably riveted to theflanges of the framing member 24 as clearly indicated in Figures 2, 3and {of the drawings. The framing member 24 is preferably rounded at itscorners and the innerand outer metallic plates follow the contour oftheframing. member. By this construction asubstantially rigid door isproduced. vIt is understood, of course, that the door openingiscorrespondingly rounded at its corners. It follows from thisconstruction that all possibility of. pinching-of the door in the dooropening due to the weavingand racking of the car is avoided. The greatstrength imparted at the corners of the door by this'construction alsoavoids opening up of the joints at such corners. The framing member 24is provided with a plurality of ofiset tongues 25 and 26 formed aroundthe perimeter of said frame and extending outwardly therefrom. Thesetongues cooperate with a flange on the Z-bar frame and with a platemember 27 to pro.- vide grooves in which continuous sealing members 28may be received. Thesesealing members in their operative positionpreferably contact with wear plates providedvin the-post, lintel andthreshold members. 1 e g Positioned within the door is a wooden frame 30conforming substantially to the contour of the reinforcing frame 24s Thedoor 15 is insulated by means of a plurality of layers of com pressedinsulating material 31 between adjacent layers of which a plurality oflayers of loose insulating material 32 is positioned. 'These layers ofinsulating material are maintained in position against the inner plate23 by means of Wooden spacers 33 which may be secured in position by anysuitable means to the wood framing member 30. These wooden spacers alsomaintain the insulating layer 31 against the outer plate Theconstruction of the door has: been de-v scribed in some detail but noclaim is made herein to this construction. The door structure will formthe subject matter of another application. The door is supported forlateral movement relative to the door opening and for sliding movementtoward open and closed position by means of a hanger comprising aplurality of vertical bars 40} These bars are rotatably retained on thedoor by means of a plurality of bearings '41 and 42. The extremities ofthe bars 40 areprovided with offset portions 43 known as goose necks.Secured to each of the vertical bars 40 is an operating lever 44 pivotedeccentrically as indicated at 45 between the spaced flanges 45"---45provided on a collar 45 adapted to be flxed upon a bar. The outermost ofsaid flanges is of greater height than the innermost flange for apurpose hereinafter set forth. A set screw 47 is utilized to retain theportion 45 in the desired relationship upon the bar. By means of thisconstruction it is evident that the wear of the weather or sealingstrips 28 may be compensated for by varying the initial angularrelationship of the levers 44- with respect to the bars 40. Thisvariation is permitted by means of the set screws 47. It is observedthat the levers 44 move toward each other when the door is being seatedin its opening and that in the latter position these levers overlap. Theoverlapping portions are provided with aligned openings 48, throughwhich a staple 49, carried by the door, is adapted to extend. A latch 50may be utilized to retain the levers. intheir overlapped position aswell as to provide means for sealing the door.

The goose necks of the bars 40 are journaled in upper carriages 51,these carriages being. supported and guided during the sliding movementof the door by'means of a retaining member 52 mounted upon the car abovethe door opening. The lowerextremities of the bars 40 are journaled incarriages 53 which are adapted to have sliding. movement upon a track 54by means of rollers 55 provided in said carriages and having engagementwith said track.

The bearings42 utilized to rotatably maintain the bars 40 in positionupon the door constitute preferably an integral portion of a bracketmember 56 adapted to be secured to the door. This bracket member isprovided, additionally, with a forwardly projecting flange 57 from whichextend a plurality of spaced ears 58. Between these ears a hook member59 is pivoted by means of a pin- 60 extending through aligned openingsin said ears. is provided with an engaging nose portion 61 while theopposite end thereof is formed with a lug 62 adapted for engagement withthe flange 57 provided on the bracket in order to limit the upwardmovement of the hook member.

The door is limited in its sliding movement by aplurality of stops orbrackets 63.

When it is desired to move the door from its closed position within thedoor opening toward its open position, the latch 50 is disengaged fromthe staple 49 and the levers 4444 are swung outwardly. During thismovement of the levers the bars 4040 will be rotated and because of thegoose neck formations thereon the door will be moved bodily out of itsopening. During this movement of the door the outer flange 45 willengage the nose on each of the hook members 59 automatically elevatingsaid member until engagement between the nose portion and said outerflange 45 has occurred, This engagement,

One end of the hook member 59 because of the connection between thelevers 44-44 and the operating bars 4040, will maintain said bars andconsequently the carriages in which they are journaled in fixed positionduring the sliding movement of the door. The carriages, consequently,have a steady unimpeded movement along the retaining bar 52 and thetrack 54. Without this rigid positioning of the bars 40-40 during thesliding movement of the door it has been found that this movement hasbeen jerky and undesirable. In addition to providing a steady,regularmovement of the door the hanger mechanism described insures suchmovement at all times in View of the fool-proof and automaticconstruction provided.

t will be observed that the nose of each hook member 59, when saidportion is in engagement with the outer flange 45 will lie in the spacebetween said outer and inner flanges 45 It is also apparent that whenthe door has been moved out of its opening the levers will gravitate tovertical position. When it is desired to force the door into its openingeach of the levers is grasped and moved to horizontal position. Duringthis movement and because of the eccentric pivotal connection of thelevers engagement between the levers 44 and the nose 61 of the hookmembers '59 will occur and bring about automatic disengagement: o'f saidhook members with the outer flange 45 provided on the collars 45. It isnoted, furthermore, that the levers are utilized merely for swinging thedoor into and out of its opening but are not employed during the slidingmovement of the door. It is manifest, therefore, that not only is theengagement between the members 59 and the levers, 44 automatic, but thatthe disengagement of these parts occurs automatically as well.

It is apparent that numerous changes and modification in the details ofthis invention may be made. It is to be understood that all such changesand modifications are comprehended within the perview of this invention,which is to be limited only by the scope of the claims appended hereto.
